Other reference titles previously found on this site are no longer available for purchase.

For Linux-users:
There is a free open-source program known as "wine" which a user informs us enables you to run eReference on Linux computers.
We have not tested this officially so please do not buy eReference for Linux until you have downloaded the demo and tested this yourself.
Even so we make no guarantees for this configuration. For more information on the latest version of Wine (v0.9.46), please visit www.winehq.org
